I recently created an iPhone app using Xcode and storyboards. The app works perfectly on a real iPhone and the iPhone simulator, but when I test it on the iPad simulator or an actual iPad something happens with the application, and I can’t figure out what went wrong…
iPhone Simulator

iPad Simulator

I solved this problem by clicking on my main Project name in Xcode. Then I selecte the tab “info” and I changed the Main Story Board File Base Name (iPad) to my storyboard. Then it worked perfectly!
